Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(tert-Butyl) 3a-ethyl 1-benzyltetrahydropyrrolo[3,4-b]pyrrole-3a,5(1H,4H)-dicarboxylate.
5-(tert-Butyl) 3a-ethyl 1-benzyltetrahydropyrrolo[3,4-b]pyrrole-3a,5(1H,4H)-dicarboxylate (CAS 2007920-01-4), molecular formula C21H30N2O4 and molecular weight 374.47 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(tert-Butyl) 3a-ethyl 1-benzyltetrahydropyrrolo[3,4-b]pyrrole-3a,5(1H,4H)-dicarboxylate (C21H30N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 5-(tert-Butyl) 3a-ethyl 1-benzyltetrahydropyrrolo[3,4-b]pyrrole-3a,5(1H,4H)-dicarboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
